Handheld reflectance confocal microscopy: Personalized and accurate presurgical delineation of lentigo maligna (melanoma).

Background: The surgical treatment of lentigo maligna melanoma is associated with high rates of local recurrence. Handheld reflectance confocal microscopy (HH-RCM) allows for in vivo presurgical detection of subclinical lentigo maligna (melanoma) (LM/LMM).

Methods: A single-center retrospective study from December 2015 to July 2017.
